The FT-7800R ’s scanning features include a two-channel scanning capability which allows
you to operate on a VFO, Memory channel, Home channel, or Weather Broadcast Channel,
while periodically checking a user-defined “Priority” Memory Channel for activity. If a
station is received on the “Priority” Channel which is strong enough to open the Squelch, the
scanner will pause on that station in accordance with the Scan-Resume mode set via Menu
#37 (
SCAN ). See page 73.
Here is the procedure for activating Priority Channel Dual Watch operation:

3. Press and hold in the [ MHz
(
PRI
)] key for 1/2 second to activate the VFO Priority mode.
The display will remain on the VFO frequency, but ev-
ery five seconds the
FT-7800R will check the Priority
Channel (memory channel) for activity.
4. Press and hold in the [ MHz
(
PRI
)] key for 1/2 second to disable the VFO Priority mode
and exit to regular VFO operation.
Memory Priority

3. Press and hold in the [ MHz
(
PRI
)] key for 1/2 second to activate the Memory Priority
mode. The display will remain on the current memory

for activity.
4. Press and hold in the [
MHz ( PRI )] key for one second to disable the Memory Priority
mode and exit to regular memory operation.
When the Memory Bank feature is activated, the FT-7800R will check the lowest
memory channel in the Memory Bank as the priority channel.

2. Now set the
FT-7800R
for operation on a HOME channel.
3. Press and hold in the [ MHz
